Dr. Aideen Hartney:

I will make an overarching point on terminology, then I will ask my colleague to give technical answers to the questions. We have a lot about Part M versus UD and UD+. Part M is the bare minimum. It is important to be clear that it is nowhere close to UD. A house built using UD can be adapted readily, easily and in a cost-effective way if the needs of the person living in it change over time, whereas UD+ is designed from the outset to be wheelchair-accessible. It is important that we are all clear on that terminology. The potential for confusion and crossfire between technical specifications is one reason that we think it would be helpful and important if a standard could be developed in this space. That will drive delivery to the UD and UD+ levels that we require rather than the bare minimum that is currently the case. Ms O'Reilly will address the technical issues.
